Cans of beer will be snapped open in millions of American backyards this Memorial Day weekend, and while brews from the big companies like Anheuser-Busch InBev and Molson Coors will, naturally, be in the hands of many, more and more people are turning to beers from smaller craft brewers.

Indeed, craft beer surpassed 6% of the total U.S. beer market in 2012, with sales hitting $10.2 billion, according to the Brewers Association, a trade group that tracks statistics for the brewing industry.

Here are the top ten U.S. craft brewing companies, according to the Brewers Association, based on 2012 sales volume.

Founded in 1984, the Boston Beer Company, which makes Samuel Adams beers, is the top U.S. craft brewer by sales volume. The Boston, MA-based brewery sold 2.1 million barrels of beer in 2012, according to the Brewers Association.
